Space in Space
How much space have you occupied in your lifetime?
let me clarify this question:
suppose there is a second dimension filled with very dense foam
, and everywhere you walk the foam disappears. the foam is not disturbed by anything other then yourself (not your cloths nor your belongings). now when you die we see how much foam is gone in the other dimension
To be exact we have to tackle some more problems. for instance what happens to the foam for an astronaut.
So we need to take the foam in the entire universe. but if the foam is relative to earth it would not be correct for a person traveling to the moon. so we need to take the foam relative to our sun? my idea was to put it relative to the center of all mass in the universe. If you would hang still in that exact point you would not start to move because all mass of all the stars and planets pulls at you from all sides with exactly the same force.
Now to calculate how much volume this is is hard to say. We could try to determine an upper limit. for instance take the surface of the earth for a height of 170cm. that would probably be a nice upper limit don't you think?
I don't think so, cause we are on the earth and the earth moves with an approximated speed of 107km/h aroun the sun. this means that each second our body moves 28 meters. thats approximately: 28m x 1.8m² = 50.4m³
So at minimum we use up 50.4m³ of foam every second. but the universe is expanding. This implies that this value will probably be a lot higher. So its hard to put a number on it. Lets instead try to imagine how this foam hole would look. We harden the foam, drill a hole and fill it with tin. Remove the foam, how does it look?
We rotate with the earth rotation, so that causes a circular stretched over 1 day around the sun. So we get 356 circles stretched over an other circle with radius the distance from earth to the sun. the little circles with tilt back and forth on the pace of the seasons. and all that stretched in the relative speed of our solar system to the relative center of the universe.
Conclusion: getting the exact number is near impossible, and the form would be a stretched double spiral where the smallest spiral is tilting axes back and forth about 2 times over the big spring period.
Hope you could follow :p
